Hi guys,
Came out an idea. I was searching for a DIY A/DC spectrum analyzer or Oscilloscope, better using arduino with external A/D chip.
And I got some words really fresh to me, like DAQ.
My original thoughts was using a AK5397 as A/D and put the data into PC, then analyze them. However, I am not an EE. After reading AKM'S ADC datasheet, lots of questions rose in my mind.
I don't know what's next after we convert A to D, and how to sen them to PC.After tremendous searching, I saw DAQ and Labview. To me, Labview seems to be the best choice, due to it's flexibility and powerful function, a DIY oscilloscope seems likely to be done in this way. Then I think maybe we can use the inexpensive arduino as DAQ rather than some DAQ cards (>80USD).
I found a paper of Princeton. Happy to see that. Exactly what I am thinking!
My goal:
*External (interchangeable) ADC module
*Analogue interface motherboard
*Better-than-audio-grade performance with C/P reasonable
*compatible to already-existed PC-based softwares
So, any comment?
